The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is superseding Airworthiness Directive (AD) 2025-16- 12, which applied to all Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes; Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -252N, -253N, -271N, -272N, -251NX, - 252NX, -253NX, -271NX, -272NX, -253NY, and -271NY airplanes. AD 2025- 16-12 required revising the existing airplane flight manual (AFM) and the existing FAA-approved minimum equipment list (MEL), allowed replacement of each affected high-pressure bleed valve (HPV) as an optional terminating action, and prohibited the installation of affected parts. Since the FAA issued AD 2025-16-12, the FAA has determined that repetitive replacement of the HPV clips is necessary to address the unsafe condition. This AD continues to require the actions in AD 2025-16-12 and requires repetitive replacement of each affected HPV clip. The FAA is issuing this AD to address the unsafe condition on these products.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
